1 Claims. (01.91-12 The present invention relates to new and useful improvements in striping or banding machines, particularly for tumblers, but it is to be understood, of course, that a machine in accordance with the present invention may be used for omamenting other types of receptacles, such, for example, as buckets, tubs, flower pots, etc.

An important object of the invention is to provide a striping or banding machine of the type .10 including one or more applicator stations, to-

gether with novel means for delivering the tumblers or other receptacles to said stations and conveying said tumblers or other receptacles away from the stations upon the completion of the striping or banding operation.

Another important object of the invention is to provide, in a manner as hereinafter set forth, a -machine of the character described comprising novel means for applying the stripe or band to the work. v p

-Other objects of the, invention are to provide a striping or banding machine for tumblers and other receptacles which will be comparatively simple in construction, strong, durable, highly efficient and reliable in operation, compact, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification,

taken in connection with the accompanying drawings wherein like characters of reference designate co responding parts throughout the several views, and wherein:-

Figure l is a view in top plan of a striping or banding machine constructed in accordance with the present invention.

Figure '7 is a detail view'in bottom plan of the rotary table. Figure 8. is a detail view in'vertical section, taken substantially on the line 8-8 of Figure 3. Figure 9 is a view principallya-in vertical section through the rotary color pan and its supporting and driving means.

Figure 10 is a top plan view of the motor supporting bracket, showing the gear housing attached therebeneath.

Figure 11 is a detail view in perspective of the scraper.

Figure 12 is a detail view-in vertical section 5 through the applicator wheel, taken substantially on the line l2|2 of Figure 3.

Figure 13 is a detail view in perspective of the color regulator.

Figure 14 is a detail view in vertical section 10 through one of the mandrels, showing the same mounted on its supporting shaft.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a supporting l5 structure which is designated generally by the reference numeral i, said supporting structure including a base 2 which is mounted on suitable legs 3. Mounted on the base 2 in vertically spaced relation thereto is a platform I which is secured in position by bolts 5 having spacing sleeves 6 thereon.

The platform 4 includes a centrally located, vertical bearing 1 in which a tubular shaft 8 is journaied. Fixed an the upper end portion of the tubular shaft 8 is a rotary horizontal table 9 25 having bearings l0 thereon in which radial shafts H are journaled. The outer ends of the shafts ll carry tapered mandrels l2 having resilient work retaining fingers I 3 recessed therein.

.The reference numeral i4 designates a vertical shaft which extends rotatably through the tubular shaft 8 and through the base 2 of the supporting sti'nbture I. Fixed on the lower end portion of the vertical shaft 14 is a worm gear l5 which is opera- 35 tively connected, by gears Hi, to an electric motor I! mounted beneath the base 2. Any suitable means, such as a thrust collar l8, may be provided for supporting the vertical shaft M on the base 2. 40

Alsojournaled vertically,in the platform! is a. shaft [9 having a gear 20 fixed on its lower end portion. The gear 20 is driven by a gear 20' which is fixed on the shaft it between the platform 4 and the base 2. The tubular shaft 8 is driven from the shaft l9 by 9. Geneva gear designated generally by the reference numeral 2| for intermittently rotating the table 9. Fixed on the inner ends of the shafts II are beveled gears 22 which are driven by a beveled'gear 2-3 fixed on the 50 upper end portion of the shaft II, It will thus be seen that the mandrels l2 and the table Sara driven by a common source of power, said mandrels l2 being constantly rotated, the table 9 being intermittently rotated.

Mounted on the platform 4 is an applicator station which is designated generally by the reference numeral 24. The applicator'station24 includes a supporting bracket which projects from the platform 4 and beneath which is sethereby. The reference numeral 3| designates a removable pan which is mounted in the pan 28. Rising from the outer end portion of the supporting bracket 25 is a post 32 upon which a scraper 33 is hingedly mounted, as at 34. As best seen in Figure 9 of the drawings, the scraper 33 is engageable in the removable color pan 3|.

The applicator station 24 further includes an arm 35 which projects from the platform 4 adjacent the supporting bracket 25, said arm 35 having a longitudinal slot 36 in its outer portion which accommodates a bolt 31 (see Figure 4) which adjustably secures a standard 38 'on said arm 35. Pivotally mounted on the upper end portion of the standard 38 is a fork 38 having its stem portion formed to provide a threaded socket 48 into which a rod 4| is threaded-for adjustment, said rod 4| being secured by a lock nut 42. Adjustably mounted on the rod 4| is a socketed fork 43 which is secured in position by a set screw 44. Journaled in bearings 45 between the arms of the'fork 43 is an applicator wheel 45 1 which is operable in the color pan 3|, said applicator wheel being also operatively engageable with the work as it is brought to the station 24 on the mandrels l2.

It will thus be seen that the applicator wheel 48 is mounted for swinging movement in a vertical plane. Mounted on the standard 38 is a cross arm 41 in one end of which an adjusting screw 48-'is threadedly mounted and in the other end portion of. which a stop screw 481s adjustabLy threaded. The screws 48 and '48 are operatively engageable with the end portions of a spring 58 which is mounted on the standard 38 and which is engaged with the bight portion of the fork 38 for yieldingly supporting the applicator wheel 46. The adjusting screw 48 regulates the tension of the spring 58, while the screw 48 serves as a stop to limit the upward movementof the end portion of said spring 58' which is engaged with the fork 38. Mounted on the fork 43 is a resilient, bifurcated gauge 5| which straddles the applicator wheel 45 and which is adjusted through the medium of a screw 52 which is also'mounted on said fork 43. As is believed to be apparent, by operating the screw 52, the gauge 5| may be adjusted towardor away from the periphery of the applicator wheel- 45 for controlling the thickness or quantity of the coloring thereon.

For each of the mandrels l2 the table 8 has ":Iormed in its lower side a socket 53 for the reception of a spring actuated locking bolt 54 which is mounted on the. platform 4. As fllustrat ed to advantage in Figure 8 of the drawings. the bolt- 54 is slidable in a cylinder 55 which rises from the platform 4. Projecting. laterally from the bolt 54 is an arm 58 having journaled thereon a roller 51 for engagement bya 'cam'58 on the. lower face of the disk 58 of the Geneva gear-2|. The arm 55 is operable in}; vertical The tumblers are slipped on the mandrels [2.

on one side of the applicator station 24 while the table 8 is stationary. 'Ihese tumblers are then carried to the applicator station 24 where they are engaged with the yleldingly supported applicator wheel 45. When the tumblers reach the station 24, the table 8 comes to rest but the tumblers continue to spin with the mandrels l2 for transferring'a band of coloring thereto from the removable color pan 3| through the medium of the applicator wheel 46, as will be readily apparent. When a tumbler reaches the station 24, the bolt 54 engages in one of the sockets 53 for positively locking the table 8 against rotation during the striping or banding operation. Substantially simultaneously with the engagement of the disk 53 again with the star wheel, the cam 58 disengages the bolt 54 from the table 8 to permit said table to be actuated .the next step for carrying the tumbler which has been mits said wheel to be conveniently adjusted for operation on various sizes or shapes of tumblers. In Figure 2 of the drawings, the tumblers being treated are designated by the reference numeral- 63. It will be noted that the applicator wheel 45 is positioned at right angles to the surface of the tumbler with which it is engaged. When the tumblers are brought into the applicator station 24, the wheel 45 is depressed slightly thereby and maintained in yielding engagement therewith by the spring 58. The scraper or agitator 33 rides in the inner pan 3| as said pan rotates and pre-- vents settling of the pigment in the bottom thereof,as will be apparent. The removable inner pan 3| facilitates ,the use of different colors. When it is desired to remove or insert the inner pan 3|, the scraper or agitator 33 is swung to'inoperative position on its hinge 34. v

While, the machine herein illustrated is for use in applying a colored stripe to the tumbler or other receptacle, .said machine may, by a slight alteration, be utilized formaking a frosted or roughened band on the tumbler or other receptacle. This may be expeditiously accomplished by removing the color pans, etc., to-

gether with the applicator wheel 45 and substituting iorsaid applicator wheel an abrading wheel driven by any'suitable means, such as an electric motor.

II or the motor 21 for actuation thereby.

This abrading wheel may be 011-, eratively connected, for example, to the motor It is believed that-the many advantages of "a striping or banding machine constructed in accordance with the present invention will be bodiment of the invention is as illustrated and described, it is to be understood that changes lb the details of construction and in the combination and arrangement of parts may be resorted 78 readily understood and although a-preferr'ed emi to which will fall within the scope of the invention as claimed.
